Q. In the light of recent classification of living organisms into three domains of life (bacteria, archaea and eukarya), which one of the following statements is true about archaea?
A) Archaea completely differ from prokaryotes
B) Archaea resemble eukarya in all respects
C) Archaea have some novel features that are absent in other prokaryotes and eukaryotes
D) Archaea completely differ from both prokaryotes and eukaryotes
Explanation
[Solution from source] Archaea are prokaryotes that share some traits with bacteria and some with eukaryotes, and also have unique features such as ether-linked membrane lipids and distinctive cell walls. They neither completely differ from nor fully resemble the other groups, which rules out the absolute options. Answer (3).
